Question

Given the code below:

var photos = [
<% current_app_user.photos.each do |photo| %>
{ url: "<%= photo.thumbnail_uri(400, 189) %>", title: "<%= truncate(photo.name, 65) %>", path :"<%= photo_path(photo) %>" },
<% end %>
];

How would I modify it to only pull 10 photos at a time?

Initially, I’d like to generate 10, then with the click of a button append 10 more and so on.

You should do this in a controller, not in your view, but inside a controller you should do it like this:

@photos = current_app_user.photos.all(:limit => 10).map do |p| 
  { :url => p.thumbnail_uri(400, 189),
    :title => p.name,
    :path => photo_path(p) }
end

And in your view:

var photos = <%= @photos.to_json %>;

No code in your view other than what’s strictly necessary 🙂
